Kinases of two strains of Mycoplasma hyopneumoniae and a strain of Mycoplasma synoviae: an overview

摘要

Mycoplasma synoviae and Mycoplasma hyopneumoniae are wall-less eubacteria belonging to the class of Mollicutes. These prokaryotes have a reduced genome size and reduced biosynthetic machinery. They cause great losses in animal production. M. synoviae is responsible for an upper respiratory tract disease of chickens and turkeys. M. hyopneumoniae is the causative agent of enzootic pneumonia in pigs. The complete genomes of these organisms showed 17 ORFs encoding kinases in M. synoviae and 15 in each of the M. hyopneumoniae strain. Four kinase genes were restricted to the avian pathogen while three were specific to the pig pathogen when compared to each other. All deduced kinases found in the non pathogenic strain (J[ATCC25934]) were also found in the pathogenic M. hyopneumoniae strain. The enzymes were classified in nine families composing five fold groups.
